Police say they expect to arrest Callahan on explosives-related charges after he is released from the hospital.

Authorities say they discovered the cache after the 65-year-old man reported someone had broken into his home on Bronson Road on Tuesday. They came across between 150 and 200 guns, as well as tens of thousands of ammunition rounds and homemade bombs.

An official from the police department says most of the weapons appear to be legal themselves.

Officials with the FBI, Fairfield County Hazmat Team and local bomb squads responded to the scene, and forced nearby residents to evacuate.
